[G4] G4 start up problems

[Tony Gamble]

Just yesterday I had a similar problem with an old machine.   
Everything was getting power, drives were spinning up, etc... but no  
chime and no display.  Sometimes would turn on from the tower power  
button, sometimes would only respond to the keyboard power key.   
Turned out to be a bad stick o' RAM.  The Beast works fine now.
